An overview of the processes that drive social cohesion. The text offers a quick guide to Complex Systems, and how communication technologies have shaped the cohesion of society.

From the wooden teeth of George Washington to the Bly prosthesis, popular in the 1860s and boasting easy uniform motions of the limb, to today's lifelike approximations, prosthetic devices reveal the extent to which the evolution and design of technologies of the body are intertwined with both the practical and subjective needs of human beings.

The peculiar history of prosthetic devices sheds light on the relationship between technological change and the civilizing process of modernity, and analyzes the concrete materials of prosthetics which carry with them ideologies of body, ideals, body politics, and culture.

Simultaneously critiquing, historicizing, and theorizing prosthetics, Artificial Parts, Practical Lives lays out a balanced and complex picture of its subject, neither vilifying nor celebrating the merger of flesh and machine.

An A-to-Z overview of eugenics - one of the most controversial scientific and cultural movements of the last century Eugenics - the theory that we can improve future generations of humans through selective breeding - was one of the most controversial movements of the early 20th century. Often tied to racist beliefs and nativist desires to limit immigration, the eugenics movement attracted some of the most prominent scientists and social reformers of the day. This encyclopedia brings into one place concise descriptions of the leading figures, organizations, events, legislation, publications, concepts, and terms of this vitally important historical movement. Although focused on the United States during the heyday of the movement, the encyclopedia includes material on international events as well as connections to important contemporary issues such as genetic engineering, family balancing, and the possibility of human cloning. 250 entries on such topics as: inherited conditions such as alcoholism, prostitution, poverty, and criminality that eugenicists thought could be eliminated by following eugenic methods; concepts such as feeblemindedness, race degeneracy, and race suicide that were pervasive during the era of the eugenics movement; tools that eugenicists relied on, such as laws that allowed forced sterilizations of the unfit; organizations that encouraged the fit to produce more children; the continued acceptance of attempts to improve future generations through genetic testing and treatment. The book includes photographs, a chronology of events, and an extensive bibliography of works for further information.. Examines a controversial aspect of scientific history. Discusses how contemporary controversies over genetic engineering relate to the eugenics theories of the past

In 1981 David Quammen began what might be every freelance writer's dream: a monthly column for Outside magazine in which he was given free rein to write about anything that interested him in the natural world. His column was called "Natural Acts," and for the next fifteen years he delighted Outside's readers with his fascinating ruminations on the world around us. The Boilerplate Rhino brings together twenty-six of Quammen's most thoughtful and engaging essays from that column, none previously printed in any of his earlier books.

In lucid, penetrating, and often quirkily idiosyncratic prose, David Quammen takes his readers with him as he explores the world. His travels lead him to rattlesnake handlers in Texas; a lizard specialist in Baja; the dinosaur museum in Jordan, Montana; and halfway across Indonesia in search of the perfect Durian fruit. He ponders the history of nutmeg in the southern Moluccas, meditates on bioluminescent beetles while soaking in the waters of the Amazon, and delivers "The Dope on Eggs" from a chicken ranch near his hometown in Montana.

Quammen's travels are always jumping-off points to explore the rich and sometimes horrifying tension between humankind and the natural world, in all its complexity and ambivalence. The result is another irrepressible assortment of ideas to explore, conundrums to contemplate, and wondrous creatures to behold.

In Pi ( ) in Nature, Art, and Culture Marcel Danesi revisits the importance of as a pattern in the structure of reality, fitting in with the Pythagorean view of Order. Pi has cropped up in formulas that describe natural and physical structures which, on the surface, seem to have nothing to do with a circle, but might harbor the archetype of circularity as a principle. Through , this book thus revisits the implicit ancient Greek view that geometry was a 'hermeneutic science,' a discipline aiming to investigate the connectivity among numbers, shapes, and natural phenomena. It also examines its manifestations in aesthetic, symbolic and cultural structures, which point to an abiding fascination with the circle as an unconscious archetype. Hermeneutic geometry is ultimately about the exploration of the meanings of geometric-mathematical notions to science and human life.

"The Elusive Wow" tells the story of the Wow signal-one of the most intriguing radio signals ever seen by searches for broadcasts from the stars. Author Robert Gray reports on the original detection and tells of his searches for the signal, showing examples of what searchers see with interstellar radios. In addition to telling the tale of the elusive signal, Gray surveys the Search for Extraterrestrial Intelligence, also known as SETI-explaining why many scientists think Others might exist on other worlds and how we might find them. Gray's scientific work has appeared in journals such as Astrophysical Journal and Icarus, and in magazines like Sky & Telescope.

The physical world is infinitely complex, yet most of us are able to find our way around it. We can walk through unfamiliar streets while maintaining a sense of direction, take shortcuts along paths we have never used and remember for many years places we have visited only once. These are remarkable achievements.

In Wayfinding, Michael Bond explores how we do it: how our brains make the ‘cognitive maps’ that keep us orientated, even in places that we don’t know. He considers how we relate to places, and asks how our understanding of the world around us affects our psychology and behaviour.

The way we think about physical space has been crucial to our evolution: the ability to navigate over large distances in prehistoric times gave Homo sapiens an advantage over the rest of the human family. Children are instinctive explorers, developing a spatial understanding as they roam. And yet today few of us make use of the wayfaring skills that we inherited from our nomadic ancestors. Most of us have little idea what we may be losing.

Bond seeks an answer to the question of why some of us are so much better at finding our way than others. He also tackles the controversial subject of sex differences in navigation, and finally tries to understand why being lost can be such a devastating psychological experience.

For readers of writers as different as Robert Macfarlane and Oliver Sacks, Wayfinding is a book that can change our sense of ourselves.

This book is a selective and fascinating history of scientific speculation about intelligent extraterrestrial life. From Plutarch to Stephen Hawking, some of the most prominent western scientists have had quite detailed perceptions and misperceptions about alien civilizations: Johannes Kepler, fresh from transforming astronomy with his work on the shape of planetary orbits, was quite sure alien engineers on the moon were excavating circular pits to provide shelter; Christiaan Huygens, the most prominent physical scientist between Galileo and Newton, dismissed Kepler's speculations, but used the laws of probability to prove that "planetarians" on other worlds are much like humans, and had developed a sense of the visual arts; Carl Sagan sees clearly that Huygens is a biological chauvinist, but doesn't see as clearly that he, Sagan, may be a cultural/technological chauvinist when he assumes aliens have highly developed technology like ours, but better.
Basalla traces the influence of one speculation on the next, showing an unbroken but twisting chain of ideas passed from one scientist to the next, and from science to popular culture. He even traces the influence of popular culture on science--Sagan always admitted how much E. R. Burroughs' Martian novels influenced his speculations about Mars. Throughout, Basalla weaves his theme that scientific belief in and search for extraterrestrial civilizations is a complex impulse, part secularized-religious, and part anthropomorphic. He questions the common modern scientific reasoning that life converges on intelligence, and intelligence converges on one science valid everywhere. He ends the book by agreeing with Stephen Hawking (usually asafe bet) that intelligence is overrated for survival in the universe, and that we are most likely alone.

What on earth do bananas have to do with quantum mechanics? From a modern perspective, quantum mechanics is about strangely counterintuitive correlations between separated systems, which can be exploited in feats like quantum teleportation, unbreakable cryptographic schemes, and computers with enormously enhanced computing power. Schro?dinger coined the term "entanglement" to describe these bizarre correlations. Bananaworld - an imaginary island with "entangled" bananas - brings to life the fascinating discoveries of the new field of quantum information without the mathematical machinery of quantum mechanics. The connection with quantum correlations is fully explained in sections written for the non-physicist reader with a serious interest in understanding the mysteries of the quantum world. The result is a subversive but entertaining book that is accessible and interesting to a wide range of readers, with the novel thesis that quantum mechanics is about the structure of information. What we have discovered is that the possibilities for representing, manipulating, and communicating information are very different than we thought.

Why do smart people make irrational decisions every day? The answers will surprise you. Predictably Irrational is an intriguing, witty and utterly original look at why we all make illogical decisions. Why can a 50p aspirin do what a 5p aspirin can't? If an item is "free" it must be a bargain, right? Why is everything relative, even when it shouldn't be? How do our expectations influence our actual opinions and decisions? In this astounding book, behavioural economist Dan Ariely cuts to the heart of our strange behaviour, demonstrating how irrationality often supplants rational thought and that the reason for this is embedded in the very structure of our minds. Predicatably Irrational brilliantly blends everyday experiences with a series of illuminating and often surprising experiments, that will change your understanding of human behaviour. And, by recognising these patterns, Ariely shows that we can make better decisions in business, in matters of collective welfare, and in our everyday lives from drinking coffee to losing weight, buying a car to choosing a romantic partner.

Provides an overview of the complex history of the interaction of science and religion. Can science and religious belief co-exist? Many people - including many practicing scientists - insist that one can simultaneously follow the principles of the scientific method and believe in a particular spiritual tradition. But throughout history there have been people for whom science challenges the very validity of religious belief. Whether called atheists, agnostics, skeptics, or infidels, these individuals use the naturalism of modern science to deny the existence of any supernatural power. This book chronicles, in a balanced and accessible way, the long history of the battle between adherents of religious doctrines and the nonbelievers who adhere to the naturalism of modern science. Science and Nonbelief provides a nontechnical introduction to the leading questions that concern science and religion today: what place does evolution hold in the arguments of nonbelievers?; what does modern physics tell us about the place of humanity in the natural world?; how do modern neurosciences challenge traditional beliefs about mind and matter?; what can scientific research about religion tell us and psychics? The volume also addresses the political context of debates over science and nonbelief, and questions about the nature of morality. It includes a selection of provocative primary source documents that illustrate the complexity and varieties of nonbelief. Part of the Greenwood Guides to Science and Religion series, this book includes a discussion of scientific attitudes to pseudo-science and the paranormal. A primary source section illustrates views on the relationship between science and belief. It adopts a balanced approach to the questions raised.

A brilliant new voice in science writing shows why playfulness and curiosity are the key to science.

Why would anyone research how elephants pee? Or study worms who tie themselves into a communal knot? Or quantify the squishability of a cockroach? It all sounds pointless, silly, or even disgusting.

Maybe it is. But in The Salmon Cannon and the Levitating Frog, Carly Anne York shows how unappreciated, overlooked, and simply curiosity-driven science has led to breakthroughs big and small. Got wind power? You might have humpback whales to thank. Know anything about particle physics? Turns out there is a ferret close to the heart of it all. And if you want to keep salmon around, be thankful for that cannon! The research itself can seem bizarre. But it drives our economy. And what’s more, this stuff is simply cool.

York invites readers to appreciate the often unpredictable journey of scientific exploration, highlighting that the heart of science lies in the relentless pursuit of knowledge for its own sake. Emphasizing the hard work of the people behind the discoveries, this is an accessible, story-driven book that shows how important and exciting it is to simply let curiosity run wild.

In this sweeping book, applied mathematician and popular author David Orrell questions the promises and pitfalls of associating beauty with truth, showing how ideas of mathematical elegance have inspired-and have sometimes misled-scientists attempting to understand nature. Orrell shows how the ancient Greeks constructed a concept of the world based on musical harmony; later thinkers replaced this model with a program, based on Newton's "rational mechanics," to reduce the universe to a few simple equations. He then turns to current physical theories, such as supersymmetric string theory-again influenced by deep aesthetic principles. The book sheds new light on historical investigations and also recent research, including the examinations ongoing at the Large Hadron Collider. Finally, broadening his discussion to other fields of research, including economics, architecture, and health, Orrell questions whether these aesthetic principles reflect an accurate way to explain and understand the structure of our world.

An expert palaeoarchaeologist reveals how our understanding of the evolution of our species has been transformed by momentous discoveries and technological advancements. Who are we? How do scientists define Homo sapiens, and how does our species differ from the extinct hominins that came before us? This illuminating book explores how the latest scientific advances, especially in genetics, are revolutionizing our understanding of human evolution. Paul Pettitt reveals the extraordinary story of how our ancestors adapted to unforgiving and relentlessly changing climates, leading to remarkable innovations in art, technology and society that we are only now beginning to comprehend. Drawing on twenty-five years of experience in the field, Paul Pettitt immerses readers in the caves and rockshelters that provide evidence of our African origins, dispersals to the far reaches of Eurasia, Australasia and ultimately the Americas. Popular accounts of the evolution of Homo sapiens emphasize biomolecular research, notably genetics, but this book also draws from the wealth of information from specific excavations and artefacts, including the author's own investigations into the origins of art and how it evolved over its first 25,000 years. He focuses in particular on behaviour, using archaeological evidence to bring an intimate perspective on lives as they were lived in the almost unimaginably distant past.

'If you feel you are in a black hole, don't give up. There's a way out' What is inside a black hole? Is time travel possible? Throughout his extraordinary career, Stephen Hawking expanded our understanding of the universe and unravelled some of its greatest mysteries. In What Is Inside a Black Hole? Hawking takes us on a journey to the outer reaches of our imaginations, exploring the science of time travel and black holes. 'The best most mind-bending sort of physics' The Times Brief Answers, Big Questions: this stunning paperback series offers electrifying essays from one of the greatest minds of our age, taken from the original text of the No. 1 bestselling Brief Answers to the Big Questions.

What is concentrated Dark Matter? Can we hack memory? Are you living in a simulation operating at 5% capacity? Rick and Morty may seem like the most idiotic show on TV today, but a lot of its crazy adventures are actually based on real-life scientific theories and cutting-edge academic research. Using the biology, chemistry and physics of the series, expert science writer Matt Brady explains the biggest questions occupying the greatest minds today, including: can we have cool cybernetic implants, will we ever be able to alter our basic intelligence, how far will we be able to go with cloning, could we travel to parallel universes, what energy could you get from a microverse battery and can you control a cockroach's nervous system with your tongue? So, become more Rick and less Morty with this wander through the portal of modern-day science. Or just go back to laughing at the stupid jokes.

From the 1950s to the digital age, Americans have pushed their childrento live science-minded lives, cementing scientific discovery and youthfulcuriosity as inseparable ideals. In this multifaceted work, historian RebeccaOnion examines the rise of informal children's science education in thetwentieth century, from the proliferation of home chemistry sets after WorldWar I to the century-long boom in child-centred science museums. Onionlooks at how the United States has increasingly focused its energies over thelast century into producing young scientists outside of the classroom. Sheshows that although Americans profess to believe that success in the sciencesis synonymous with good citizenship, this idea is deeply complicated inan era when scientific data is hotly contested and many Americans have aconflicted view of science itself. These contradictions, Onion explains, can be understood by examiningconnections between the histories of popular science and the developmentof ideas about American childhood. She shows how the idealised concept of"science" has moved through the public consciousness and how the drive tomake child scientists has deeply influenced American culture.

AMERICAN MATHEMATICAL SOCIETY COLLOQUIUM PUBLICATIONS VOLUME XXXI FUNCTIONAL ANALYSIS AND SEMI-GROUPS BY EINAR HILLE PROFESSOR OF MATHEMATICS YALE UNIVERSITY PUBLISHED BY THE AMERICAN MATHEMATICAL SOCIETY 531 WEST 116iH STREET, NEW YORK CITY 1948 To KIRSTI And each man hears as the twilight nears, to the beat of his dying hearty The Devil drum on the darkened pane You did it, but was it Art FOREWORD The analytical theory of semi-groups is a recent addition to the ever-growing list of mathematical disciplines. It was my good fortune to take an early interest in this disci pline and to see it reach maturity. It has been a pleasant association I hail a semi-group when I see one and I seem to see them every where Friends have observed, however, that there are mathematical objects which are not semi-groups. The present book is an elaboration of my Colloquium Lectures delivered before the American Mathematical Society at its August, 1944 meeting at Wellesley College. I wish to thank the Society and its officers for their invitation to present and publish these lectures. The book is divided into three parts plus an appendix. My desire to give a practically self-contained presentation of the theory required the inclusion of an elaborate introduc tion to modern functional analysis with special emphasis on function theory in Banach spaces and algebras. This occupies Part One of the book and the Appendix these portions can be read separately from the rest and may be used as a text in a course on operator theory. It is possible to cover most of the material in these six chapters in two terms. The analytical theory of one-parameter semi-groups occupies Part Two while Part Three deals with theapplications to analysis. The latter include such varied topics as trigonometric series and integrals, summability, fractional integration, stochastic theory, and the problem of Cauchy for partial differential equations. In the general theory the reader will also find an alternate approach to ergodic theory. All semi-groups studied in this treatise are referred to a normed topology semi-groups without topology figure in a few places but no details are given. The task of developing an adequate theory of trans formation semi-groups operating in partially ordered spaces is left to more competent hands. The literature has been covered rather incompletely owing to recent war conditions and to the wide range of topics touched upon, which have made it exceedingly difficult to give the proper credits. This investigation has been supported by grants from the American Philosophical Society and from Yale University which are gratefully acknowledged. On the personal side, it is a great pleasure to express my gratitude to the many friends who have aided me in pre paring this book. J. D. Tamarkin, who read and criticized my early work in the field and who vigorously urged its inclusion in the Colloquium Series is beyond the reach of my grati tude. I am deeply indebted to Nelson Dunford and to Max Zorn who have contributed extensively to the book, the former chiefly to Chapters II, III, V, VIII, IX, and XIV, the latter to Chapters IV, VII, and XXII. Both have given me generously of their time and special experience. Various portions of the manuscript have been critically examined and amended by Warren Ambrose, E. G. Begle, H. Cramdr, J. L. Doob, W. Feller, N. Jacobson, D. S. Miller, II. Pollard, C.E. Rickart, and I. E. Segal. To all helpers, named and un named, I extend my warmest thanks. EINAK HILLE New Haven, Conn., December, 1946 CONVENTIONS Each Part of the book starts with a Summary, each Chapter with an Orientation.

The astonishing story of twentieth-century physics, told through the twelve experiments that changed our world A 2022 BOOK OF THE YEAR FOR: NEW SCIENTIST * WATERSTONES * SUNDAY TIMES 'A splendid idea, vividly carried out: I enjoyed this book enormously’ PHILIP PULLMAN 'A rich history of beautiful discoveries' ROBIN INCE 'An all-action thriller, laced with some of the most profound ideas humans have ever had’ BRIAN ENO ----------- How did a piece of gold foil completely change our understanding of atoms? What part did a hot air balloon play in the discovery of cosmic rays? How did the experiments in the run-up to the Large Hadron Collider lead to the invention of the World Wide Web? Asking questions has always been at the heart of physics, our unending quest to understand the Universe and how everything in it behaves. How do we know all that we know about the world today? It’s not simply because we have the maths – it’s because we have done the experiments. Accelerator physicist Suzie Sheehy introduces us to the creative and curious people who, through a combination of genius, persistence and luck, staged the ground-breaking experiments of the twentieth century. From the serendipitous discovery of X-rays in a German laboratory, to the scientists trying to prove Einstein wrong (and inadvertently proving him right), The Matter of Everything takes us on a journey through the history of experiments that transformed our world.

Quadratic equations, Pythagoras' theorem, imaginary numbers, and pi - you may remember studying these at school, but did anyone ever explain why? Never fear - bestselling science writer, and your new favourite maths teacher, Michael Brooks, is here to help. In The Maths That Made Us, Brooks reminds us of the wonders of numbers: how they enabled explorers to travel far across the seas and astronomers to map the heavens; how they won wars and halted the HIV epidemic; how they are responsible for the design of your home and almost everything in it, down to the smartphone in your pocket. His clear explanations of the maths that built our world, along with stories about where it came from and how it shaped human history, will engage and delight. From ancient Egyptian priests to the Apollo astronauts, and Babylonian tax collectors to juggling robots, join Brooks and his extraordinarily eccentric cast of characters in discovering how maths made us who we are today.

This book explains - in simple terms and with almost no mathematics - the physics behind recent and glamorous discoveries in Cosmology, Quantum Mechanics, Elementary Particles (e.g. Higgs bosons) and Complexity Theory. En route it delves into the historical landmarks and revolutions that brought about our current understanding of the universe. The book is written mainly for those with little scientific background, both college students and lay readers alike, who are curious about the world of modern physics. Unsolved problems are highlighted and the philosophical implications of the sometimes astounding modern discoveries are discussed. Along the way the reader gains an insight into the mindset and methodology of a physicist.

**A FINANCIAL TIMES BOOK OF THE YEAR 2022** 'Powerful... a clarion call for change', New Statesman 'Poetic and philosophical at times, intimate and expansive at others', Daily Telegraph How much light is too much light? The Darkness Manifesto urges us to cherish natural darkness for the sake of the environment, our own wellbeing, and all life on earth. The world's flora and fauna have evolved to operate in the natural cycle of day and night. But constant illumination has made light pollution a major issue. From space, our planet glows brightly, 24/7. By extending our day, we have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things. Our cities' streetlamps and neon signs are altering entire ecosystems. Johan Ekloef encourages us to appreciate natural darkness and its unique benefits. He also writes passionately about the domino effect of damage we inflict by keeping the lights on: insects failing to reproduce; birds blinded and bewildered; bats starving as they wait in vain for insects that only come out in the dark. And humans can find that our hormones, weight and mental well-being are all impacted. Eye-opening and ultimately encouraging, The Darkness Manifesto offers simple steps that can benefit ourselves and the planet. The light bulb - long the symbol of progress - needs to be turned off. To ensure a bright future, we must embrace the darkness
